Last Wednesday, the New York State Public Service Commission (PSC) ruled that municipal power companies could charge higher electricity rates to cryptocurrency miners who try to benefit from the state's abundance of cheap hydroelectric power. Ars Technica reports: Over the years, Bitcoin's soaring price has drawn entrepreneurs to mining. Bitcoin mining enterprises have become massive endeavors, consuming megawatts of power on some grids. To minimize the cost of that considerable power draw, mining companies have tried to site their operations in towns with cheap electricity, both in the U.S. and around the world. In the U.S., regions with the cheapest energy tend to be small towns with hydroelectric power. But mining booms in small U.S. towns are not always met with approval. A group of 36 municipal power authorities in northern and western New York petitioned the PSC for permission to raise electricity rates for cryptocurrency miners because their excessive power use has been taxing very small local grids and causing rates to rise for other customers. The PSC responded on Wednesday that it would allow those local power companies to raise rates for cryptocurrency miners. The response noted that New York's local power companies, which are customer-owned and range in size from 1.5 MW to 122 MW, "acquire low-cost power, typically hydro, and distribute the power to customers at no profit." If a community consumes more than what has been acquired, cost increases are passed on to all customers. "In Plattsburgh, for example, monthly bills for average residential customers increased nearly $10 in January because of the two cryptocurrency companies operating there," the PSC document says. The city of Plattsburgh, New York has since imposed an 18-month moratorium on commercial cryptocurrency mining to "protect and enhance the city's natural, historic, cultural and electrical resources."
